The Biden administration on Saturday issued a final rule aimed at reducing methane emissions, targeting the U.S. oil and natural gas industry for its role in global warming, as President Joe Biden seeks to advance his climate legacy.

The Environmental Protection Agency said the rule will sharply reduce methane and other harmful air pollutants generated by the oil and gas industry, promote use of cutting-edge methane detection technologies and deliver significant public health benefits in the form of reduced hospital visits, lost school days and even deaths. Air pollution from oil and gas operations can cause cancer, harm the nervous and respiratory systems and contribute to birth defects.

EPA Administrator Michael Regan and White House climate adviser Ali Zaidi announced the final rule at the U.N. climate conference in the United Arab Emirates. Separately, the president of the climate summit announced Saturday that 50 oil companies, representing nearly half of global production, have pledged to reach near-zero methane emissions and end routine flaring in their operations by 2030.

Oil and gas operations are the largest industrial source of methane, the main component in natural gas and far more potent than carbon dioxide in the short term. It is responsible for about one-third of planet-warming greenhouse gas emissions. Sharp cuts in methane emissions are a global priority to slow the rate of climate change and are a major topic at the conference, known as COP28.

Smaller wells included

The methane rule finalizes a proposal Biden made at a UN climate conference in Scotland in 2021 and expanded a year later at a climate conference in Egypt. It targets emissions from existing oil and gas wells nationwide, rather than focusing only on new wells, as previous EPA regulations have done. It also regulates smaller wells that will be required to find and plug methane leaks. Such wells currently are subject to an initial inspection but are rarely checked again for leaks.

Studies have found that smaller wells produce 6% of the nation’s oil and gas but account for up to half the methane emissions from well sites.

The plan also will phase in a requirement for energy companies to eliminate routine flaring of natural gas that is produced by new oil wells.

The new methane rule will help ensure that the United States meets a goal set by more than 100 nations to cut methane emissions by 30% from 2020 levels by 2030, Regan said.

The new rule will be coordinated with a methane fee approved in the 2022 climate law. The fee, set to take effect next year, will charge energy producers that exceed a certain level of methane emissions as much as $1,500 per metric ton of methane. The plan marks the first time the U.S. government has directly imposed a fee, or tax, on greenhouse gas emissions.

The law allows exemptions for companies that comply with the EPA’s standards or fall below a certain emissions threshold. It also includes $1.5 billon in grants and other spending to help companies and local communities improve monitoring and data collection and find and repair natural gas leaks.

Reaction positive

Harold Wimmer, president and CEO of the American Lung Association, called the new rule a victory for public health.

“EPA heeded the urgent guidance of health experts across the country and finalized a strong methane rule that, when fully implemented, will significantly reduce hazardous air pollutants and climate-warming methane pollution from the oil and gas industry,” he said in a statement.

Methane has been shown to leak into the atmosphere during every stage of oil and gas production, Wimmer said, and “people who live near oil and gas wells are especially vulnerable to these exposure risks. This rule [is] vital to advancing environmental justice commitments.”

David Doniger, a climate expert at the Natural Resources Defense Council, called methane a “super-polluter.” He said in an interview that the Biden plan “takes a very solid whack at climate pollution. I wish this had happened 10 years ago, but I’m really happy it’s happening now.”

The oil industry has generally welcomed direct federal regulation of methane emissions, preferring a single national standard to a hodgepodge of state rules. Even so, energy companies have asked the EPA to exempt hundreds of thousands of the nation’s smallest wells from the pending methane rules.
